In researching our branch of the Katzenberger family (Margaretha Katzenberger/Hermann Beyer), we have collected numerous data items on Katzenberger families in NYC around the turn of the last century. Whether the families connect in Germany requires additional research. We are currently in the process of organizing the many data items. I do believe the MC of Augusta is one you would be interested in as it contains a legible place of birth. I will send it to your EMail address.
